Prince William Talks Princess Charlotte, Prince George on 1st Day of New Job

— -- Britain’s Prince William became a dad for the second time two months ago and today began another new chapter in his life, a new job as an air ambulance pilot.

William, 33, told reporters he was “feeling the nerves” on his first day working at East Anglian Air Ambulance. The prince’s first shift, as a co-pilot with medical staff, will be nearly 10 hours long, the BBC reported.

"It's a follow-on from where I was with the military search and rescue with many of the same sorts of skills, so it was a natural progression,” William said of his new role, which he will work in a schedule of four days on and four days off.

William, who will donate his salary to charity, took the job last August after spending four years with the Royal Air Force Search and Rescue.

The second-in-line to the British throne will balance his piloting duties with his official royal duties and his family duties. Prince William and his wife, Princess Kate, are parents to nearly 2-year-old Prince George and 2-month-old Princess Charlotte.

"Obviously, at some point there is going to be a lot more pressure and responsibility from the other side of my life, but at the moment I'm juggling the two of them and a young family and I'm enjoying the challenge,” William said.

Prince William called his youngest daughter a “little joy of heaven” and his son, the very active Prince George, a “little monkey," according to the U.K.'s The Telegraph.

"But it is fantastic having a lovely little family and I am so thrilled,” William said. “And Catherine has been doing an amazing job as a mother and I’m very proud of her.

“You never know what is going to happen in the future,” William went on to say when asked whether the couple planned to have more children.

In his day job, Prince William is part of a crew that is “called to an average of four incidents per day,” including, “life threatening situations such as road traffic accidents and medical emergencies,” according to East Anglian Air Ambulance website.

The prince told reporters he hopes taking on a job different from his royal duties will help keep him “grounded.”

"For me it is also really important to be grounded,” William said. “I feel doing a job like this really helps with grounding the core of what I am trying to become… just trying to be a good guy, trying to do what you can, trying be a decent individual, thoughtful…qualities in people that you would want to be associated with.”
